| titleOfInvention | Method of regenerating catalyst based on titanium-containing zeolite for epoxidation of propylene |
| abstract | FIELD: chemistry.SUBSTANCE: present invention relates to catalyst regeneration method. Described is a method of regenerating a catalyst containing zeolite containing titanium, with a MWW frame structure, as a catalytically active material, comprising (i) a step comprising (a) continuously producing propylene oxide, comprising (a1) feeding a stream of feed material containing propene, hydrogen peroxide or a hydrogen peroxide source, and acetonitrile, into a reactor containing a catalyst containing said titanium-containing zeolite with a MWW framework structure as a catalytically active material; (a2) exposing the flow of incoming material according to (a1) in the reactor to epoxidation conditions in the presence of said catalyst to obtain a reaction mixture containing propylene oxide and acetonitrile; (a3) removing a stream of product containing said propylene oxide and acetonitrile from the reactor; (b) stopping introduction of flow of incoming material into reactor; (c) washing the catalyst with a liquid aqueous system; wherein step (i) further includes repeating sequence of steps (a) - (c) n times, where n is an integer and is equal to at least 1; wherein said regeneration method further comprises (ii) a step comprising calcining a catalyst obtained on (c) after repeating the sequence of steps (a) to (c) n times, where said calcination is carried out at temperature of catalyst in range from 300 to 600 °C, using a gas stream containing oxygen, wherein washing the catalyst with a liquid aqueous system according to step (c) of step (i) is carried out at least once without subsequent calcination; where the sequence of steps (i) - (ii) is not necessarily repeated m times, wherein m is an integer and is equal to at least 1, where, during each repetition of sequence of stages (i) - (ii), n is identical or different.EFFECT: technical result is creation of simple and economical method of catalyst regeneration, improved selectivity.16 cl, 2 ex, 2 tbl, 2 dwg |
